AUTOMATIC DOUBLE-SEAMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 693,303, dated February 11, 1902.

Application filed July 8. 1901. Serial No. 67,460- (No model.)

To all whom, it may concern:

Be it known that we,EDwIN NORTON, residing in the city of New York, in the county of New York and State of New York, and

JOHN G. HODGSON, residing in the village of Maywood, in the county of Cook and State of Illinois, citizens of the United States, have invented a new and useful Improvement in Automatic Double Seaming Machines, of

to which the following is a specification.

Our invention relates to machines for double-seaming covers onsheet-metal cans.

The object of our invention is to provide a machine of a simple, efficient, and durable constructiomby means of which this work may be done withcertainty and uniformity and so as to form hermetically-tight and perfect double seams and which will be automatic and rapid and cheap in operation.

2o Our invention consists in the combination,

with an intermittently-rotating turret or table provided with a series of rotating canholder chucks or disks and with ejectors for the cans, of a rotating and reciprocating canholder chuck into registry with which the series of can-holder chucks or disks on theretating turret or table are brought in turn by the intermittent movement of said turret or table, and a continuously-rotating tool-carrier provided with a series of sets of double-seaming tools or rollers, the several tools of each set being brought successively into operation upon each can by the rotating tool-carrier during the period of pause of the can-holder 3 5 turret or table, and a succeeding set of tools being brought into position for operation upon the next can by the further movement of the tool-carrier while the can-holder turret or table is making its next forward step or movement.

Our invention also consists in the novel devices and in the novel combinations of parts and devices herein shown and described, and specified in the claims.

'45 In the accompanying drawings, forming a part of this specification, Figure 1 is a front View of a machine embodying our invention. Figs. ,2 and 3 are side elevations looking from opposite sides of the machine. Figs. 4: and 5 5c are horizontalsections on the lines at 4 and 5 5,

erably rests on springs 27.

respectively, of Figs. 1', 2, and 3. Fig. 6 is a vertical section through the turreton the line 6 6 of Fig.7. Fig. 7 is an enlarged detail plan view of the spider and mechanism for rotating and locking the turret. Fig. 8 is a 5 5 detail elevation, partly in section, of the upper can-holder chuck. Figs. 9 and 10 are detail views of the cams for operating the upper chuck and its ejector. Figs. 11, 12, 13, and 1 1 are enlarged diagrammatic views rep- 6o resenting the operation on the can. u

In said drawings, 15 represents the frame ofthe machine.

16 is an intermittently-rotating can-holder turret or table, the same being. provided with a series (preferably six) of rotatable canholder chucks or disks 17, each having a countersunk seat 18 for the can, the same being formed'of a rubber or elastic cushion 19, secured to the disk 17 by lugs 20-entering'7o suitable recesses in the disk 17 therefor. Each of the disks or chucks 17 has a hollow stud 21, in which fits the stem 22 of the can-ejector disk 23, which serves to lift the can out of the countersunk seat 18 after the doubleseaming operation has been completed, so that the finished can may be delivered from the machine automatically by the stationary can-ejector or delivery-arm 100 as the table or turret 16 revolves. Ball-bearing collars 8o 24 25 and balls 26 are preferably interposed between the rotating disk or chuck 17 and the turret or table. The collar 25 also pref- -The can-holder turret or table 16 is intermittently rotated and accurately locked in position to cause each of the can-holder chucks 17 to accurately register with the upper rotating and reciprocating can-holder chuck or disk 27. The rotating chuck or disk 27 is furnished 0 with a countersunk seat 28 to receive the ejector-disk 29 and with a shoulder 30 to fit within the countersunk head or cover 31 of the can 32, the flange 33 of which cover is. to be folded into a double seam 34: with the ,9 5 flange 35 of the can-body, thus compressing the packing 36 andforming a strong, rigid, air-tight joint. The can ejector or stripper disk 29 is secured to the stem or stud 37 having a collar 38 and spring 39, which holds the loo ejector-disk normally retracted, so that the same is out of contact with the can except when the stud or stem 37 is engaged by the sliding rod 40, which operates the ejector to discharge the can. The chuck or disk 27 is secured to a hollow shaft 41, which is rotated by a bevel-gear 42, splined thereto to permit the necessary sliding movement, and which meshes with a bevel-gear 43 on the driving shaft 44, which receives its power from the pulley 45 and belt 46. The necessary up and down movement is communicated to the upper chuck or disk 27 from the driving-shaft 47 through the gears 48 49, shaft 50, bevelgears 51 52, cam 53, and lever 54, which is connected to the chuck-shaft 41 through collars 55 56, balls 58 being inserted between the collars 55 56. The ejector-operating rod 40 is operated as required by a lever 57 and pitman 58, connected to the disk 59 on the shaft 105.

60 is a continuously-rotating tool-carrier, the same being provided, preferably, with three sets of double-seaming rollers or tools 61 62 63, each set of double-seaming tools preferably comprising three grooved rollers or tools, each journaled on the periphery of the circular tool-carrier disk, so that. as the tool-carrier disk revolves the three tools of each set will be brought successively into contact with the flanges of the can cover and body, and thus operate to fold the same into a double seam. Continuous rotary movement is communicated to the tool-carrier through a Worm-gear 64 on the shaft 65 of the tool-carrier, worm 66 on the shaft 67, gears 68 69 on shaft 70, and gears 71 72, the latter being on the driving-shaft.

The can-holder turret or table 16 is intermittently rotated and accurately locked in position as required by means of a Geneva stop-gear, comprising a disk 73, having radial slots 74 and circular recesses 75 and rotating shaft 76, carrying arm 77, roller 75, and mutilated disk 79. Motion is communicated to the shaft 76 through the bevel-gears 80 81, bevel-gears 82 83, shaft 84, and gears 85 S6.

The can-ejector disk 23 or its stem 22 is 0perated bya stationary cam 90, with which the stem 22 engages as the can-holder turret rotates. The tool-carrier is mounted upon an adjustable slide 91, which may be adjusted in position to cause the double-seaming tool to properly operate upon the can whatever its size by means of the hand adjusting-screw 92. The can-holder turret is carried upon a vertically-adjustable bracket 93, which may be adjusted up and down as required to operate on cans of different heights by means of the hand adjusting-screw 94.

After the cans have been double-seamed by the operation of the machine the cans are automatically discharged by the ejector-arm into the discharge-chute 101.

The turret or table 16 is provided with brakes or plates 102, which engage brake flanges or surfaces 103 on the rotating chucks or disks 17 when the springs 27 raise said chucks or disks, thus automatically stopping the rotation and facilitating the putting of the cans in the disks. When the upper rotary-driven chuck or disk 27 is depressed, it depresses the lower disk 17 and throws it automatically out of contact with the brake, thus leaving it free to rotate with the upper chuck and the can-head between the two.

The shaft 70, through which motion is communicated from the driving-shaft 47 to the worm and worm-gear by which the tool-carrier is rotated, is provided with a flexible connection or coupling 106 to permit the neces sary up-and-down adjustment of the tool-car rier by the adjusting-screw 107. The shaft 70 is splined to the gear 69 to permit the inand-out adjustment of the tool-carrier by the adjusting-screw 92.
